Ordered these at the start of my pumping journey. Enjoyed them so much, and the price point was so good, that I ordered another 2 sets to make cleaning a little easier. Had great output and the customer service with this company is outstanding. I can’t recommend these pumps enough. They come with extra spare parts and even a few set of flange sizes too (17/19/21/24). Easy to insert your size if they don’t come with yours.

Love them! One of the Motors when out after exclusively pumping for 6 months but I was able to contact them and have it replaced with the one year warranty that comes with them when bought. Now at 8 months and going strong!

This is a great pump and does a wonderful job expressing my milk. I'm a second time mom and an over-producer. My first time around I gave birth to twins and used the Spectra pump and was able to breastfeed until I chose to stop just after 1 year. This time around I had a singleton and my boobs still produce a ton of milk, but I've returned to work earlier (first time I went back for half days at 3 months until over 1 year, this time I'm back full time at 3 months) and I wanted to find something that didn't necessarily require me to leave my desk 3 times a day. Pros: Great suction - I get just as much (sometimes more!) milk with this pump as I do with my lansinoh pump. 3-5 ounces per breast each time. Relatively quiet! I mean you can definitely hear it, but I can turn on my little desk space heater to drown it out in my otherwise silent shared office. Fits inside my nursing bras. Mostly easy to clean - kind of hard to get in a couple of the little corners but not a huge deal to me, I do use a 21mm flange insert so I have 5 parts from each pump to clean Cons: Charging - while they charge up pretty quickly, there is no way to tell what the current charge is while the pump is on, only when charging. It would be nice to have a display to show remaining battery bc several times it's happened that one will just die in the middle of a pump session - very frustrating. Also the motors look exactly the same so you dont know which one you just charged! I ended up using a sharpie to write 'A' on one and 'B' on the other so I could kind of keep track of which one needed charging. Please make the battery status display a thing!! Memory function - it's nice that the pump remembers the suction level you use on each setting, but I wish it didn't start up on whichever mode it ended on. Sometimes I forget to switch from "expression" to "stimulation" at the end of a session so the next time I power it on it will start up on a strong expression mode which is a shock and uncomfortable. The way around it is to always switch back to stimulate mode before turning off, but would be much more user friendly to just make that the automatic starting point each time you power it on. Somewhat tricky to position - just the design of the pump makes it so you can't see your nipples inside the flange so you can't tell if they're positioned properly (for instance to make sure they won't rub the sides or aren't being sucked too far into the flange), not sure if there's a fix for it, just a tricky thing to get right. Looks a little silly - I am small chested (A cup) and wearing this makes me look a little ridiculous, as if I have DDs lol while it doesn't look COMPLETELY unnatural, anyone that knows me knows my boobs are that big lmao All in all, this is a great pump and has become my main pump. I actually get upset if I forget it and have to use my hospital grade pump. It does just as good a job as my lansinoh and is so worth the money, just could use a few tweaks for user friendliness! Photos show my 13 minute morning pump session. BF baby at 6:45 and then pump at work at 10:15.

I can’t express enough how much I love this pump I have went through so many different wearable pumps and this one is by far the best. It is even better than my mom cozy. It expresses so much better than my primary pump, but I would have your bag ready because after 15 minutes they might be full and it holds up to 7 ounces each

The pumps worked very well at first. So well that I retired my Spectra when I was using MomMed. After daily consistent use for three months, one of the pumps gave out and was no longer able to perform like it used to. Because the company claimed to offer lifetime warranty, I reached out to them for assistance with replacing it. UNREASONABLE and ABSOLUTELY INAPPROPRIATE experience with MomMed customer service: If I could give them negative 10 stars, I would. I sent an email to MomMed asking for assistance with replacing the pump that stopped working. The customer service rep who assisted me (Joy), tried to blame Amazon stating that "violent transportation" probably damaged the product (even though the pumps and package arrived in perfect condition and worked fine for the first three months). Her first request was for me to provide her a video of the the pump malfunctioning. As requested, I provided a short video of the pumps on my counter that showed one side full of milk and the other with barely anything. The video made it very clear that one pump was no longer operating like it should. She responded and made a second request, asking if I had record of how much breast milk I typically produce when I pump, so that she could compare. As requested, I provided a photo of what I produced using my Spectra pumps and explained that I was able to pump the same amount using MomMed until it stopped working. She then responded and made a third request, asking me to provide a 20 minute video of myself pumping so that she could compare the amount of milk I produce and stated that I am not allowed to edit the video. I explained that I already provided a video of what I produced with MomMed and then a photo of what I produced using Spectra pumps. Which she clearly stated "photos or videos are welcomed". The video and photo I provided showed a very clear comparison between the two brands. She then let me know that since the video and photo I provided were taken after I had finished pumping, it wasn't enough evidence for them to determine if the pumps are not repairable and needed me to provide a 20 minute video of me pumping without edits instead. First of all, that's the dumbest and most outrageous thing I've ever heard. How on earth would anyone know if the pumps are not repairable from a video of me pumping. Second of all, what an invasive and outrageous ask, to ask women to provide 20 minute videos of themselves pumping to god knows where. I let her know that that was an extremely invasive ask and that I'm not comfortable recording or sharing that with anyone. I also let her know that I'd be leaving a negative review about my experience. She only offered to replace the pumps AFTER my comment about leaving a negative review. It was an extremely frustrating process and I ended up going through Amazon for a replacement instead. They basically market that they offer Lifetime warranty just to make themselves look good, but then make the process so difficult that no one is actually able to get a replacement. I also saw that another woman left a review with a very similar experience as well, so it seems like this is just how they run their business unfortunately.

I’ve only used this pump once and I can already tell I like it so much more than my Momcozy S12 Pro! I only meant to pump for about 10–15 minutes and didn’t even realize I had been pumping for 23 minutes 😂 That’s how quiet it is and how comfortable the suction feels! I also love that it comes with different flange size options, which made a huge difference for me. So far, I’m extremely happy with this purchase and definitely recommend it! UPDATE: I wanted to come back and update my review after using this pump longer. I genuinely loved it in the beginning, and I still think the suction is GREAT. Unfortunately, that’s about the only thing I still love about it. After continued use, I’ve cut my fingers multiple times taking it apart to clean because some of the edges and little openings are surprisingly sharp. The motor also gets STUCK on top and can be ridiculously hard to remove. I’ve had milk leak around the sides of the flange and even through the nipple opening, which is especially frustrating when you worked hard for that milk. 😭 Another thing I didn’t notice immediately is how top-heavy it is. It tips over SO easily, and because the motor can be nearly impossible to get off, you’re basically stuck trying to balance the entire pump while dealing with your milk. I really wanted to continue loving this pump because the suction/output was honestly impressive at first. But after actually living with it, cleaning it constantly, getting cut, fighting to get the motor off, and losing milk from leaks/spills, I unfortunately can’t recommend it the way I originally did. Great suction, but the overall design needs some serious improvement.

I really love this pump it’s fast and not too loud. I would say to buy a breast pump spray because it will get stuck to the skin and it will hurt when removing from the breast but overall a life saver being able to be mobile while pumping!

I am in looooove. I’ve had it for four months now and everyone told me that I’d still need a “primary” pump like the spectra but I was exclusively pumping and hated my spectra. These mommeds made life bearable again. I got just as good output with them (pro tip: I love the legendairy pumping spray), they were recommended by my lactation consultant, not crazy expensive like other pumps, and don’t hurt like my spectra did. If I am wearing a sweatshirt I’ll even leave my car/house briefly with them (though I prefer pumping in privacy). They fit in my nursing bras well, stay put, and I’ve literally never had a single problem with leaking like my friends do with their other brands of wearable pumps. I recommend these pumps to all my friends and my friends who have gotten them love their pumps, too. My friend sent me a text that said, “The Mommed pumps? LIFE-CHANGING.” And it’s true. She took hers on an airplane and said they were fabulous. Because who the heck wants to bring a massive Spectra machine on a plane and become a cow being milked for 20 minutes? No one. I’ll say they definitely aren’t silent, but they’re not loud either. They come with so many extras - little bags for the pumps, extra duckbills, extra back flow protectors, inserts to make the flange the correct size for your nipple, and even a cute little pumping guide. These helped me go from not pumping enough for my little guy to even having a bit of an oversupply and freezer storage! They didn’t have the light up ones when I bought mine, but I feel like I would love the lights to let me know how full they are/help me when I’m pumping at night. But trust me when I say: when you get these, you can put your spectra up on a nice, high shelf and never touch it again. I’m obsessed.
